Gefitinib is a type of drug called a tyrosine kinase inhibitor (TKI), also known as a cancer growth inhibitor. Kinases are proteins in the body that regulate how the cells grow and divide. Gefitinib blocks (inhibits) the protein from sending signals to the cancer cells that make them grow and divide.

USES:

Gefitinib is used to treat some people with non-small cell lung cancer (NSCLC). It only works for cancers that have an abnormal form of a protein called epidermal growth factor receptor (EGFR). Tests are done on the cancer cells from a lung biopsy or previous surgery to check the level of EGFR.
